Provide a concise summary of the key points about black holes mentioned here: Black holes are regions of space where gravity is so strong that nothing, not even light, can escape from them. They form when massive stars collapse under their own gravity at the end of their life cycles. Black holes can be detected through their interactions with nearby matter and the radiation emitted as matter is pulled into them. There are different types of black holes, including stellar and supermassive black holes found at the centers of most galaxies.

Black holes have gravity so strong that light cannot escape, form from collapsing stars, interact with matter and emit radiation, and come in types like stellar and supermassive, often found in galaxy centers.

Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Please briefly sum up what this article says about orcas' bodies. 

Orcas are known for their long dorsal fin (the fin on the animal's back) and black-and-white coloring. The black-and-white coloring helps to camouflage them by obscuring their outline in the water. Just behind the dorsal fin is a patch of gray called a "saddle" — because it looks like a riding saddle. 

An orca's body is cylindrical and tapers at each end to form a hydrodynamic shape. This shape, along with the orca's large size and strength, makes it among the fastest marine mammals, able to reach speeds in excess of 30 knots (about 34 mph, or 56 km/h). Orcas have massive teeth, which can grow up to 4 inches (10 centimeters) long, according to National Geographic.
Response: Orcas have teeth up to 4 inches long, long dorsal fins, black-and-white camouflage coloring, and gray saddles on their cylindrical, hydrodynamic-shaped bodies. They are among the fastest marine mammals, reaching over 30 knots (34 mph or 56 km/h).

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.
